Application January 19, 1939, Serial No. 251,808 1 Claim. (cum-c) Thepresent invention relates to new and useful improvements in tire toolsand has for its primary object to provide, in a manner as hereinafterset forth, a device of this character comprising novel means forcompressing or collapsing deflated pneumatic tires in a manner tofacilitate the removal thereof from drop center rims.

Another'very important object of the invention is to provide a tool ofthe aforementioned character which is adapted to be expeditiouslyadjusted for different sizes of tires.

Other objects of the invention are to provide a tire tool of thechaarcter described which will be comparatively simple in construction,strong, durable, highly efficient and reliable in use, compact and whichmay be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification,

taken in connection with the accompanying drawing wherein likecharacters of reference designate corresponding parts throughout theseveral views, and wherein:

Figure l is a view in side elevation of a tire tool. constructed inaccordance with the present invention.

Figure 2 is a plan view thereof.

Figure 3 is a cross sectional view on an enlarged scale, takensubstantially on the line 3-4 of Fig. 1.

Figure 4 is a cross sectional view, taken substantially on the line 4-4of Fig. 1.

Figure 5 is a detail view in perspective of the adjustable rim engaginglug.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises a pairof spaced, parallel bars I of suitable metal. Extending from one end ofthe bars I are integral hooks 2. Bolts 3 which are provided with nuts 4secure the bars I and the hooks 2 together. The reference numeral 5designates spacers between the bars I and between the hooks 2. One

, of the bars 1 includes a longitudinal extension 6' on one end whichterminates in a handle I.

The bars I have formed therein longitudinally spaced, curved slots ornotches 8. The notches 8 in the bars I are transversely aligned.Pivotally mounted between the bars I is a lever 9 having a handle ID onone end. At its other end, the lever 9 terminates in a foot U which isengageabie with the outer side wallof a tire (not shown). Mountedtransversely in the lever 9 at an intermediate point is a pivot pin l2which is selectively engageable in the notches 8 for mounting saiidlever for swinging movement between the bars Adjustably mounted on thefree end portions 5 of the hooks 2 is a rim engaging the lug l3 ofsuitable metal. The lug I3 is mounted on a shank [4 which passes betweenthe hooks 2 and which has threaded thereon a wing nut l5, 0 Formed onthe lug I3 is a rib l6 which is engageable selectively in spaced notchesH which are provided therefor in the hooks 2 for securing said. lug inadjusted position in conjunction with the wing nut l5. 9

It is thought that the manner in which the tool functions will'bereadily apparent from a consideration of the foregoing. Briefly, thehooks 2 are passed over the tire to be removed and the lug I3 is engagedbeneath the lunch 0 flange of the rim. Then, by swinging the lever 9rearwardly the foot portion I I thereof is swung forwardly or toward thetire. Thus, the tire is compressed or collapsedand may be removed fromthe rim with a minimum of effort. As here- 25 1 inbefore mentioned, thefoot portion ll of the lever 9 engages-the outer side wall of the tire.By adjusting the lug l3 and the lever 9the device is readily adapted foruse on different sizes oi tires. 0

It is believed that the many advantages of a tire tool constructed inaccordance with the praent invention will be readily understood andalthough a preferred embodiment of the device is as illustrated anddescribed, it is to be understood that changes in the details ofconstruction and in the combination and arrangement ofparts may beresorted to which will fall within the scope of the invention asclaimed.

What is claimed is:

A tire tool comprising a pair of opposed bars 40 connected in spacedrelation, a hook on one end of each bar, said hooks being connected inspaced relation and having spaced notches in the inner sides thereof, arim engaging lug 'adjustably mounted on the hooks and including a ribengageable selectively in the notches, a shank on the lug extendingthrough the space between the hooks, a retaining nut threaded on saidshank, and-a hand lever mounted for swinging movement on the bars andengageable with a tire.
